I know of no such feature in "classic" Aironet APs. Everything I've run across only does classic 802.11-style DCF along with all the stations. You might check out the Aironet 1550, which supports forming dynamic mesh-like topologies, though I can't speak to it as I've never laid hands on the hardware or software. Other vendors and hackers are implementing alternative media-access control and coordination functions, though. You might check out Ubiquiti's AirMax-speaking hardware or ieee80211_tdma in FreeBSD for software MAC-capable drivers. Cheers, jof
